The RO3073E is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic case.  
It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at  
approximately 315 MHz. This SAW was designed for AM transmitters in automotive-keyless-entry  
applications operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.

Aging may exceed the specification for prolonged temperatures above +65°C.  
Typically, aging is greatest the first year after manufacture, decreasing in  
subsequent years.
